Specification of Letters Patent.

Application filed Octoberfi, 1917. Serial No. 195,531.

To all whom it may concern:

Be it known that we, EDWIN B. CANTRELL and GEORGE E. MILLER, citizens ofthe United States, residing at the city and county of San Francisco andState of California, have invented new and useful Improvements inWheel-Pullers, of which the following is a specification.

This invention relates to a wheel puller.

One of the objects of the present inven tion is to provide a simple andsubstantial form of wheel puller comprising a capshaped member, one endof which is internally threaded and sufficiently large to be received bythe threads provided for the hub cap. Another objectof the invention isto split the threaded enlarged end of the puller and to provide anexternal, tapered thread for the reception of a nut to permit the splitsections of the puller to be contracted to securely grip the threads ofthe wheel hub when the puller is applied.- Another object of theinvention is to provide a screw which is carried by the puller and sopositioned that it may engage the end of the wheel axle andexertsulficient pressure when turned to pull the wheel off of Furtherobjects will hereinafter appear. V

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which t Figure 1 is a sideelevation of the wheel puller.

Fig. 2 is a central, longitudinal section through the puller, showing itapplied to a wheel and in position to remove it from the axle.

Referring to the drawings in detail, A indicates, in general, acap-shaped casing, one end of which is internally threaded, as at 2. andsuiiiciently large to be received by the cap threads 3 formed on a wheelhub 4. The opposite end of the casing is entirely closed and providedwith a nut-likeextension 5, through which extends a screw 6.

Formed externally of the enlarged end is a slightly tapered threadedsection 7, and adapted to be received by said threaded section is a nut8 which may be turned by means of a removable handle or rod 9. Theenlarged section of the casing carrying the threaded sections 2 and 7 issplit into six or more sections, as shown at 10, thereby permitting thenut 8, when turned, to contract the sections and materially reduce theinside diameterthereof when it is applied.

The a lication of the puller is shown in Fig. 2. o use it, it is onlynecessary to remove the hub cap and to screw on the casing A in placethereof. The nut 8 is then turned until the split sections securely gripthe threaded portion of the hub and it is then onlynecessary to turn thescrew 6 by means of a wrench or other suitable tool until it exerts itspressure against the end 011: tihe vaxle 11 and pulls the wheel 03 ofthe s a t.

The wheel puller may be constructed of tool steel, if desired, and may,therefore, serve the function of a die; that is, aslight contraction ofthe split end of the casin permits cleaning or renewing of the threa swhere they have been crossed or otherwise damaged, thereby serving as acombination die and screw jack and a contractible clamp. The casing maybe made sufiiciently large to handle any sized wheel and axle desired,and the materials and finish ot the several parts of the device may besuch as the experience and judgment of the manufacturer may dictate. 7

Having thus described our invention, what we claim and desire to secureby Lethers Patent is-- I A wheel puller comprising a cap-shaped easing,one end of which is split into a plurality of sections and externallyand internally threaded, a nut adapted to be received by the externalthreads, and a screw received by the opposite end of the casing andextending longitudinally therethrough.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
